Schoolboy error! Harry Styles misses flight to visit Taylor Swift for New Year after leaving his passport at home

It's one of the most dreaded moments when you head off on your holidays - leaving your passport at home.

And it was one that became reality for Harry Styles on Friday morning when his scatty ways meant he missed a flight to visit girlfriend Taylor Swift in Boston for their New Year celebrations.

The One Direction star arrived at London's Heathrow Airport after being driven by his mother following their Christmas celebrations at home.

And he risked missing seeing in 2013 with his country star partner after the big mishap.

But in true pop star style he decided to splash out and get a courier to go and pick up his passport from his home in Cheshire 180 miles away and get on the next available flight.

After initially being scheduled to depart the airport at 11.15am, Harry finally managed to depart Britain on the 7.30pm flight.

Clearly keen to get to Taylor as soon as possible, Styles was even left to kill several hours at the airport before he could fly out of the country.

And perhaps a little embarrassed by his blooper, the singer was seen walking through the airport with his head bowed, wearing a wooly beanie hat and a black coat.

Inseparable: Harry had to pay for a courier to travel 180 miles to his home in Cheshire so he could get on the next available flight - eight hours later

A source told the Sunday People: 'Harry was due to fly out on Friday morning and his mum very kindly offered to drive him to the airport, but when he got there he realised he didn't have his passport...

'He managed to get on the evening flight but it still meant that he had to wait another eight hours for his post-Christmas reunion with Taylor.

'Despite this, he took the whole event in good humour and ridiculed himself for it.'

The
former X Factor star had been back in England spending time with his
family over Christmas, while Swift was in Nashville with her own
parents.

It is reported
they plan to spend New Year's Eve in New York, where Taylor will be
performing alongside Justin Bieber for Dick Clark's New Year's Rockin'
Eve in Times Square.

Harry and Taylor first met in America earlier this year when he was touring the country with his One Direction bandmates.

But
their relationship failed to ignite until more recently when they were
photographed getting cosy and holding hands during a stroll around the
Big Apple's Central Park.

And
over the last month they have become increasingly inseparable, with
Swift even flying to Britain to enjoy a romantic break near his Cheshire
home for her 23rd birthday.

Clearly
smitten, the pair even enjoyed a skiing break in Utah together, before
Styles managed to drag himself away and flew home on Christmas Eve.
